SparkFun RFID Glass Capsule (125kHz) ID Walkie Talkies This is a good spoolThis is a glass, cylindrical RFID tag; its very similar to those implanted into pets for identification purposes. But really guys, its not for use inside your body. Please dont implant this thing into yourselves. Each tag comes with a unique 32 bit ID code and is not reprogrammable. The carrier frequency of this tag is 125kHz, so it works great with our ID 3LA, ID 12LA and ID 20LA RFID readers. We tested this RFID tag with one of our ID 12LA readers
